Its U-shape provides natural shelter from prevailing winds, resulting in consistently calm, crystal-clear waters ideal for snorkeling. The reef hosts over 15 named snorkel sites including Rayban, Mojo, and Blue Lagoon, each offering distinct terrain — from shallow coral gardens of staghorn and plate coral, sandy gullies, and bommies to deep oceanic walls. Visibility ranges 12-18 m, and the array of habitats supports dazzling fish life, turtles, and reef sharks. A low-impact tourism zone, it's accessed only by select eco-certified operators.","beginner",null,"published",{"name":59,"amplitude":75,"phase":91,"latitude":22,"model":107,"epoch":108},[60,61,62,63,64,65,66,67,68,69,70,71,72,73,74],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[76,77,78,79,80,81,82,83,84,85,86,87,88,89,90],0.025580295110738865,0.020046305451213806,0.31064892603436545,0.08828830785589976,0.5259547325523163,0.0025086716360606066,0.010746721612930355,0.009429977957650612,0.1807110233433356,0.14990280521912674,0.08586485194207952,0.02404703524075214,0.009613696600104277,0.3071574009102365,0.03121600905706292,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],317.8572534678261,49.91842728773078,39.97824457463802,299.3038290304229,344.0502872041597,214.91240974572833,2.8915254547487104,39.39175289910723,328.2179553766016,11.883865103027343,37.76388970356343,357.50539116891935,348.74862687254114,304.1273229118612,272.57923720556926,"EOT20","1992-01-01T00:00:00Z",[110,114,119,123,126],{"name":111,"description":112,"severity":113,"season_start":56,"season_end":56},"Tidal Currents","Some sites (e.g., Plato, South North Opal) experience strong tidal currents that can sweep snorkelers off course.
